Vanda plant named &#39;SPCDW1103&#39;

ABSTRACT

A new and distinct  Vanda  cultivar named ‘SPCDW1103’ is disclosed, characterized by petals and sepals colored white with light purple netting. The new variety is a  Vanda,  typically produced as an indoor ornamental plant.

LATIN NAME OF THE GENUS AND SPECIES

Vanda hybrid

VARIETY DENOMINATION

‘SPCDW1103’

BACKGROUND OF THE INVENTION

This application relates to a new cultivar of Vanda, as described in EUapplication number 2011/2164, filed Sep. 12, 2011, grant pending, towhich applicant claims priority. The new variety is the product of aplanned breeding program. The new variety originated as a seedling fromthe crossing of the unpatented, proprietary seed parent Vanda ‘G248815’with the unpatented, proprietary pollen parent referred to as Vanda‘CTRV1815’. The crossing was made by the inventor in his researchgreenhouse in Chonburi, Thailand in October of 1987.

The new variety was first selected by the inventor, ThumrongSuphachadiwong, a citizen of Thailand, in June 1993, in a researchgreenhouse belonging to the inventor in Chonburi, Thailand. Afteridentifying the new variety as a potentially interesting selection, theinventor continued confidential testing and propagation of ‘SPCDW1103’,assessing stability of the unique characteristics of this variety.

Asexual reproduction of the new cultivar ‘SPCDW1103’ was first performedat a commercial laboratory belonging to the inventor in Chonburi,Thailand by tissue culture in March of 1998. Access to all plants wasrestricted, as plants were kept in a greenhouse not open to the public,and tissue culture plantlets were in a laboratory belonging to theinventor, and not accessible to the public. Through subsequentpropagation by vegetative cuttings, multiple generations have beenreproduced, which have shown that the unique features of this cultivarare stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘SPCDW1103’ has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, day length, and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘SPCDW1103.’ These characteristics incombination distinguish ‘SPCDW1103’ as a new and distinct Vandacultivar:

1. Unique sepal and petal coloration of white with light purple netting.

2. Improved plant compatibility for commercial growing methods.

PARENT COMPARISON

Plants of the new cultivar ‘SPCDW1103’ are similar to the seed parent,Vanda ‘G248815’ in most horticultural characteristics. The new variety,however, produces flowers with a different color than the seed parent.

Plants of the new cultivar ‘SPCDW1103’ are similar to the pollen parent,Vanda ‘CTRV1815’ in most horticultural characteristics. The new variety,however, produces flowers more easily than the pollen parent.

COMMERCIAL COMPARISON

‘SPCDW1103’ is similar in most horticultural characteristics to theunpatented commercial variety Vanda ‘Blue Magic’ in most horticulturalcharacteristics. The new variety, however, produces sepals and petalscolored white with light purple netting, whereas ‘Blue Magic’ producespetals and sepals that are white with a thick, dark purple netting.Additionally, the new variety has a lip colored medium purple, whereas‘Blue Magic’ has a lip color of dark purple.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color atypical plant of ‘SPCDW1103’ grown in a commercial greenhouse inHonselersdijk, the Netherlands. This plant is approximately 5.5 yearsold, shown planted in a 8 cm container. The photograph was taken usingconventional techniques and although colors may appear different fromactual colors due to light reflectance it is as accurate as possible byconventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The RoyalHorticultural Society Colour Chart 2001, except where general terms ofordinary dictionary significance are used. The following observationsand measurements describe ‘SPCDW1103’ plants grown in a greenhouse inHonselersdijk, the Netherlands. Temperatures ranged were approximately23° C. during the day and 19° C. at night. No photoperiodic or chemicaltreatments were given to the plants. When natural lighting fell below150 Watt, artificial lighting is given at 10,000 lux for 16 hours a day.Measurements and numerical values represent averages of typical planttypes.
